via device tree overlay , as usual - https://github.com/raspberrypi/linux/bl ... 1-L4105C68you wouldn't know how to expose pwmchip1 in linux 6.12 ?according to the CM4S data sheet https://datasheets.raspberrypi.com/cm4s ... asheet.pdf they are.
CM4 does not expose GPIO40/41 on the connector.
Code:
Legal pin,function combinations for each channel: PWM0: 12,4(Alt0) 18,2(Alt5) 40,4(Alt0) 52,5(Alt1) PWM1: 13,4(Alt0) 19,2(Alt5) 41,4(Alt0) 45,4(Alt0) 53,5(Alt1)Statistics: Posted by aBUGSworstnightmare — Fri Jul 25, 2025 12:19 pm
